A head-up display device that is configured to allow a driver to intuitively recognize a plurality of objects sequentially along a travel route of a vehicle while projecting a video onto an image forming plane that has a length in the vertical direction shorter than a length in the horizontal direction. An optical processor of the head-up display device obtains from a controller a first image signal based on the nearest road sign information and a second image signal based on the following road sign information along the travel route. The optical processor causes line segment objects as well as information objects generated from the first image signal and the second image signal, respectively, to be displayed on an image forming plane.

Head-up display device

There are provided right and left side-rearward cameras, an inside camera to detect a driver's eyeball position, main HUDs comprising projectors to form virtual images by projecting image information picked up by the cameras to reflecting mirrors and drive portions to adjust positions of the virtual images, and a ECU to control the projectors and the drive portions. The controller is configured to perform the process of calculating a distance between the eyeball position and a normal virtual-image display position which is located at a front end and an end portion, in a vehicle width direction, of a bonnet, and controlling the main HUDs such that a normal main view vis displayed at the normal virtual-image display position.

Display apparatus for vehicle

There is provided a vehicle driving support device including: a change amount calculating partthat calculates a first correlation value correlated to a change amount of acceleration of a vehicle; a jerk calculating partthat calculates a second correlation value correlated to a jerk of the vehicle; and an operation state determining partthat determines a driving operation state of the vehicle from a first correlation value calculated by a change amount calculating part, and a second correlation value calculated by a jerk calculating part, in accordance with a determination reference previously set from a ratio of a kinetic energy of a mass point to the change amount of the acceleration of the vehicle at an end point of change when the acceleration of the vehicle is changed, calculated using a vibration model showing a movement of the mass point in a passenger compartment.
